A few of us in Adelaide use our 18v blowers to pump in 90% of the air (to about 2 psi) then top up by hand - and find it works well. A barbed plumbing reducer and 3/4" poly tube is a neat enough fit over the pump hose end.
Separately, I haven't had any issues with the Tuomico pump and don't know anyone who has (a lot of people use them here), however, I have wondered about how safe they are and always charge mine sitting on concrete.
